Yes I know those are good brands... but I can't afford those. The price is at least 2x higher.
This tecnoware 550W has 12v rail rated at 26A, and tecnoware 650W 25A 12v rail. I'm pretty sure they won't be able to run any high end cards despite 550w or even 650w rating. But what about radeon 5770 and phenom X6 1090? is that enough power? I want to buy tecnoware 550W, but don't want scenario when you start a game computer restarts.
